I was going to use the seaweed fert once a week.
Should I not do this now?

what is the nitrogen ratio on it?
i put seaweed in/around the tomatoes when i plant them, then
don't fertilize again.
with the mushroom compost, i think you're probably set. over
fertilizing will get you lots of growth, & leaves, but few
blossoms.

The 'roma' variety is the only one which is flowering. The
rest are growing but very slowly . Should I fertilize them?

they've been in for only a week. patience is a virtue. wait a
few more weeks.
